ABSTRACT:
An atmospheric environmental monitoring method utilizes a corrosion test element prepared from a transparent substrate having two opposed surfaces. A corrodable film is applied to one surface of the substrate in the form of a thin wedge of metal and a security coating is applied to the opposite surface of the substrate. The surface of the corrodable film adjacent to the transparent substrate is reflective to radiation when viewed through the substrate. The security layer is designed to reflect radiation in at least the visible region of the spectrum and yet be transparent to radiation in other parts of the spectrum.
